Abstract

The characteristic properties of high power laser beams are the time and spatial dependent power density distribution, the power, the polarization and the so called focusability, d ,^χ which is the product of beam diameter and beam divergence. These four parameters have a large influence on penetration depth and/or processing speed during material processing as sell 23 on the quality of the processed material. In the following two measuring devices are explained to measure the above mentioned properties of a 5 kW-CO₂-laser beam with the exception of the polarization degree.
